A data warehouse commonly referred to as an enterprise data warehouse (EDW), is a tool for reporting and data analysis and is regarded as a key part of business intelligence.  DWs serve as the central repository for combined data from a variety of sources. They maintain both historical and current data in one place that is used to provide analytical reports for employees across the company.

The operational systems upload the data that is kept in the warehouse (such as marketing or sales). Before being used in the DW for reporting, the data may go via an operational data storage and could require data cleansing for extra procedures to ensure data quality.

Therefore, a data warehouse is organized around important subject areas.
